Dynamics of propene adsorption on Ag001.
The interaction of propene with Ag(001) is investigated by high resolution electron energy loss spectroscopy and supersonic molecular beam methods under ultra high vacuum conditions. Propene adsorbs molecularly at 110 K and desorbs intact leaving a clean surface after annealing to 160 K. Two adsorption sites, characterized by slightly different vibrational modes, exist. The low frequency specie...
متن کاملInequivalent measures of noncompactness
Two homogeneous measures of noncompactness β and γ on an infinite dimensional Banach space X are called “equivalent” if there exist positive constants b and c such that bβ(S) ≤ γ (S) ≤ cβ(S) for all bounded sets S ⊂ X . If such constants do not exist, the measures of noncompactness are “inequivalent.”Weask a foundational questionwhich apparently has not previously been considered: For what infi...
متن کامل4-manifolds with inequivalent symplectic forms and 3-manifolds with inequivalent fibrations
We exhibit a closed, simply connected 4-manifold X carrying two symplectic structures whose first Chern classes in H(X,Z) lie in disjoint orbits of the diffeomorphism group of X. Consequently, the moduli space of symplectic forms on X is disconnected. The example X is in turn based on a 3-manifold M . The symplectic structures on X come from a pair of fibrations π0, π1 : M → S whose Euler class...
متن کاملInequivalent Transitive Factorizations into Transpositions
The question of counting minimal factorizations of permutations into transpositions that act transitively on a set has been studied extensively in the geometrical setting of ramified coverings of the sphere and in the algebraic setting of symmetric functions. It is natural, however, from a combinatorial point of view to ask how such results are affected by counting up to equivalence of factoriz...
متن کاملInequivalent Quantizations of Gauge Theories
It is known that the quantization of a system defined on a topologically non-trivial configuration space is ambiguous in that many inequivalent quantum systems are possible. This is the case for multiply connected spaces as well as for coset spaces. Recently, a new framework for these inequivalent quantizations approach has been proposed by McMullan and Tsutsui, which is based on a generalized ...
